ATTACHMENT FOR THERMOS-BOTTLES.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed July 9, 1919. Serial No. 309,671.

To all whom it may concern:

Be it known that we, CONNIE H. WILsoN and CHARLEs G. LEE, citizens of the United States, residing at Asheville, in the county of Buncombe and State of North Carolina, have invented a new and useful Attachment for Thermos-Bottles, of which the following is a specification.

This invention relates to attachments for thermos bottles and the like, and has for an object the provision of means for uniformly distributing the temperature throughout the inner bottle of the usual thermos bottle structure, thereby preventing the bottle from cracking or breaking when suddenly subjected to extreme temperatures.

Another object of this invention is to provide an attachment of this character of generally improved construction, whereby the device will be simple, durable, and inexpensive in construction, as well as convenient, practical, serviceable and efficient in its use.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described,

it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiments in the accompanying drawings wherein:

Figure 1 is a side elevation of the device showing it in use in connection with the usual thermos bottle, the bottle being diagrammatically illustrated by dotted lines.

Fig. 2 is a top plan view of the device.

Fig. 3 is a side view of a modified form of the invention.

Referring to the drawing, there is shown the usual form of the thermos bottles having an outer member or casing C and the usual inner member or bottle B.

The invention comprises an elongated rod or stem 5 having a coil spring 6 secured to the lower end thereof, and the convolutions of the spring are disposed in a plane that is perpendicular to the stem 5. Separate resilient arms 7 are secured to the upper terminal of the stem 5, and each arm includes a radially extending inner portion 8, a relatively long longitudinally disposed portion 9 and radially disposed portions or fingers 10 extending from the outer terminal of the longitudinally disposed portion 9.

In use the attachment may be readily inserted into the bottle B by removing the usual stopper and contracting the coil spring 6 so that it may be passed through the neck of the bottle. Then the arms 9 are contracted or moved toward each other so that these arms may also be passed through the neck of the bottle. Now the coil spring 6 rests on the bottom of the bottle and the outer terminals of the fingers 1O engage the side wall of the neck portion of the bottle. If extremely hot or cold liquid is poured into the bottle, this attachment, owing to its relatively great conducting properties, will uniformly distribute the temperature throughout the bottle, thereby preventing the breaking or cracking of the same.

A slight modification of our invention is illustrated in Fig. 3, and includes a coil spring 6' secured to a chain 5 which is then in turn secured to and supported by the usual bottle stopper S. In use the spring 6 rests against the bottom of the bottle while the chain 5 hangs loosely from the stopper S.

Having thus described our invention what is claimed is 1. A device of the class described includ ing an elongated stem, a coil spring secured to one terminal of the stem," said spring being disposed perpendicularly to the stem to thereby allow the convolutions of the spring to engage the bottom of the receptacle, resilient arms secured to the opposed terminal of the elongated stem and adapted to engage the side wall of the re ceptacle thereby securing the device within the receptacle.

2. A device of the class described including an elongated stem, a coil spring secured to one terminal of the stem, said spring being disposed perpendicularly to the stem thereby allowing every convolution of the spring to engage the bottom of a receptacle,

and a radially disposed finger extending as our own, We have hereto aflixed our sigi'rom the outer terminal of the longinatures in the presence of two Witnesses.

tudinally disposed portion, said fingers CONNIE H. WILSON. adapted to yieldingly engage the side Wall 7 CHAS. G. LEE.

5 of the receptacle thereby securing the device Witnesses: Within the receptacle. F. R. BAKER,
